Method Detail

• build

   abstract KeyValueMatcher<KEY> build(String rule, TypedKeyManager<KEY> keyManager, TypeManagerContext contexts)

  Similar to build, the only difference is that it should use ComparisonStrategy based on TypeManager.compareTo chosen with respect to the given contexts

• build

   abstract KeyValueMatcher<KEY> build(String rule, TypedKeyManager<KEY> keyManager, ComparisonStrategy comparison, TypeManagerContext contexts)

  Generally processing logic looks as below:

  • KeyValueMatcher works on data holders which can be represented as a bag of key-value pairs

  • Given textual matching rules representations are defined in terms of target keys and their values

  • We parse the given rule representation string and extract string keys from it in factory-specific way, for example, if it's SQL rule (like k1 = 1 and (k2 < 2 or k3 in (31, 31)), we can use sql parser for that

  • Parse target keys from their string representations

  • Get value type for the target key

  • Find TypeManager for every value type (see TypeManager.targetType and TypeManager.targetContext), given contexts allow to customize that

  • Parse value objects from their string representations given in the rule string

  • Build KeyValueMatcher for the parsed keys, values an operations defined in the given matching rule string. Given ComparisonStrategy is used for that
